Great WBF! There´s something that Rand didn´t mention and it´s the fact that some social media widgets can increase credibility, reduce bounce rate and increase average time on site. For example in a niche blog that I tested, if a first time visitor arrives to a blog post a see that that particular post has been shared X times on TW, FB, etc. it is more likely that he will keep reading. I don´t expect people to share content right away, but it improved other KPIs. July 21, 2012
